Maintenance of Your Pump:

• First make sure to flush out pump with warm soapy water.
• Check to make sure there is nothing obstructing the tube or the hole in the top of the dish.
• Make sure there is enough fluid in the bottle to flow up through the tube.
  If this does not clear the pump, soak it overnight in alcohol.
